HEATING AND VENTILATING BUILDINGS.

SPECIFICATION forming part of Letters Patent No. 387,681, dated August 14, 1888.

Application filed December 20, 1886. Serial No. 222,117. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM N. HEATON, a citizen of the United States of America and resident of Des Moines, in the county of Polk and State of Iowa, have invented certain new and useful Improvements in Heating and Ventilating Buildings, of which the following is a specification.

My invention consists in the construction of a furnace and the construction and combin-ation of a ventilatingdevice with a furnace and a building, as hereinafter set forth,pointed out in my claims, and illustrated in the accompanying drawings, in WhiOl1-- Figure 1 is a side view of my furnace and ventilating device combined and in position as required for practical use in a building. Fig. 2 shows the front end of the furnace, from which the door-fran1e and facing-plate are removed to show the interior. Fig. 3 is an edge view of the plate used to close the rear end of the combustion-chamber. Fig.4 is a face view of the air-chamber connected with the rear end of the combustion-chamber. Fig. 5 is a perspective view of a section of a grate-bar. Fig. 6 shows my ventilating device applied to .a furnace of common form.

- A represents the metal wall of the combustion-chamber of my furnace. It is preferably circular in shape, as shown.

A are perforated flanges at the ends of th wall A.

Bis a metal door-frame fitted to the front end of the wall A and secured thereto by means of bolts or rivets passed through perforations in its edge that coincide with the perforations in the flanges A.

B is a metal plate fixed to the rear end of the wall in the same manner.

1 2 3 4 represent a series of tubular projections formed integral with the plate B.

c is a horizontal flange on the opposite side of the same plate, adapted, in combination with a corresponding flange on the door-frame B, to support a series of grate-bars, (Z. By means of bearings d on the plates B and B and projections d on the ends of two grate-bars, two bars can be placed in inclined positions on the opposite sides of the furnace, as clearly shown in Fig. 2, for the purpose of protecting the wall A, retaining the fuel in the central portion of the combustiouchamber, and to allow air to pass up at the sides of the wall to become heated and distributed through and around these inclined bars to envelop the fuel, to promote combustion, and prevent the annoyances and loss of heat incident to the production of soot and the fouling and clogging of flues. The bearings d serve as sockets or mortises, into which the projections or tenons cl on the ends of the grate-bars can be readily slipped in and out as required to de tachably connect the grate-bars with the plates B and B A represents a brick wall inclosing the wall A to confine the air to be heated by the furnace.

F represents a chamber and radiator connected with the rear end of the brick wall.

F represents a detachable cover or hinged door in an opening in the rear end of the wall, through which access is gained to the chamber F to clean the series of tubes 9, that connect the chamber F with the combustion-chamber of the furnace, as shown in Fig. 1. A detachable plate or hinged door, h, allows access to the tubes.

J is a smoke and draft flue that extends vertically from the combustion-chamber of the furnace to a chimney.

' J 2 is a tube extending from the chamber and radiator F to the flue J to convey the products of combustion from the furnace into that flue when a direct draft is cut off by means of a damper, J in the flue J. The wall A, the series of tubes 9, the chamber F, and the conducting-tube J 2 are thus all made available as radiators for heating cold air admitted and confined within the brick wall to be heated, and then distributed to diflerent'rooms in a building through conveying-tubes K, connectchimney. Foul air is thus drawn from rooms in a building and utilized to increase the draft of the furnace, promote the combustion of the fuel, and to aid in ventilating a building.

n represents registers fixed in the floor to regulate the passage of hot air from the tubes k.

I am aware that the products of combustion have been conveyed through tubes from a combustion'chamber in a furnace into a separate chamber for various purposes; but my manner of constructing and combining a combustion-chamber and a chamber and radiator adapted for cleaning flues with a wall is novel and advantageous.

I am also aware that ventilating-fines have been connected with apartmentsiu a building and extended through a hot air chamber inside of the furnace, and from thence into a smoke-flue, in such a manner that air would become heated in the tubes to facilitate the removal of foul air from a room; but my combination of an auxiliary chamber or drum with the outside and top of a furnace and ventilating-tubes as an extraneous attachment to carry off vitiated air is greatly advantageous, in that it can be readily applied to most all kinds of heating furnaces in use, without altering the furnace, in such a manner that it will remedy defective ventilation in buildings and also improve defective draft in the furnace by discharging the heated foul air into the furnace smokeflue or chimney.

I am also aware that a drum has been combined with a stove and a ventilating-tube extended from an apartment in a building into the base of a stove in such a manner that foul air would be conducted from the apartment into the stove to increase draft and promote combustion and to pass off with the products of combustion through the drum into a chimney; but it is often desirable to check the draft of a stove or furnace by preventing the admission of air to its base, while at the same time it is desirable to continue the carrying off of foul air from an apartmenta result that cannot be accomplished by connecting the tube for conveying foul air with the base of a stove or furnace, so that it will have communication with the fuel and fire, whereas by means of my attachment the foul air will be constantly moved from an apartment While there is heat in the stove or furnace without interfering with the shutting off of air from the fuel and fire.

I am aware, also, that a pipe has been connected with a register fixed in the wall of a chimney and extended into a smoke-flue connected with the top of a stove inclosed in the same chimney in such a manner that foul air could be conducted from an apartment outside of the chimney into the smoke-flue inclosed in the chimney. A drum has also been fixed in concentric position with a smoke-flue in a chimney at an elevated position relative to a building and the stove, and the lower end of the drum closed and the upper end left open in such a manner that a pipe connected with the drum and a register fixed in the chimney would convey heated air from the upper part of a room outside of the chimney into the drum, and from thence upward on the outside of the smoke-flue; but attaching an opentopped drum to a smoke-flue at some distance from a stove or furnace and inclosing the flue in a concentric pipe, or, in other words, making a double flue to extend from the drum into a chimney or third flue, is complicated and expensive in construction and less effectiveiu operation than my manner of combining a chamber direct with the top and radiating-surface of a furnace-wall and connecting tubes therewith to conduct foul air from apartments into the chamber to be heated therein, and then conveyed to an escape-flue through asingle plain tube that extendsfrom thesaidchamher into an escape-flue.

I claim as my invention- 1. In a furnace, the combination of the openended cylinder and wall A, having flanges A, the door-frame B, the end B, having tubular projections 1 2 3 4, the chamber F, having a door, It, and the tubes 9, and flue J, substantially as shown and described, for the purposes stated.

2. The grate-bars having projections d" on their ends, in combination with the plates 13 and B, having inclined bearings d and flanges c on their inside faces, substantially as shown and described, for the purposes stated.

3. The combination of the open-ended cylinder or wall A, having flanges A, the doorframe B, having a flange, c, and inclined bearings d, the plate 13*, having a flange, c, bearings d, and tubular extensions 1 2 3 4, the grate-bars having projections d, the chamber F, having a door, h, the tubes g, and the flues J and J, constructed and combined within a wall, A, substantiallyas shown and described, for the purposes stated.

4. The ventilating device for buildings, consisting of an auxiliary chamber attached to the outside of the heater or furnace, and tube or tubes connectedtherewith and extending into a room or rooms to be ventilated, and a tube extending from the same chamber to an escape-flue, substantially as shown and described.
